A Premier Division reserves team recently played against a side made up of
long-term prisoners from Strangeways. ('The Strangeways team were playing at home,
of course!)

The game had only been in progress for about ten minutes when the referee noticed
that the prison team were fielding twelve men. Blowing his whistle angrily, he
called the Strangeways captain over and said,

'What the hell's the idea of having twelve men on the field? Don't you know
that's illegal?'
